MIC5301
Single, 150mA µCap ULDO™
General Description
The MIC5301 is a high performance, single output
ultra low LDO (ULDO™) regulator, offering low total
output noise. The MIC5301 is capable of sourcing
150mA output current and offers high PSRR and low
output noise, making it an ideal solution for RF
applications.
For battery operated applications, the MIC5301 offers
2% accuracy, extremely low dropout voltage (40mV @
150mA), and low ground current (typically 85µA total).
The MIC5301 can also be put into a zero-off-mode
current state, drawing no current when disabled.
The MIC5301 is available in the 1.6mm x 1.6mm
MLF^® package, occupying only 2.56mm² of PCB area,
a 36% reduction in board area compared to SC-70
and 2mm x 2mm MLF^® packages.
The MIC5301 has an operating junction temperature
range of –40°C to +125°C and is available in fixed and
adjustable output voltages in lead-free (RoHS
compliant) MLF^® and Thin SOT-23-5 packages.
